IC for System Reset (with built-in watchdog timer)
Monolithic IC MM1096
March 3, 2004
Outline
This IC functions in a variety of CPU systems and other logic systems to generate a reset signal and reset the
system accurately when the power is turned on or interrupted.
It includes a watchdog timer which allows diagnosis of the system operation, so that it prevents system
runaway by intermittently generating a reset pulse when system misoperation occurs.
Built-in watchdog timer
Low current consumption
130µA typ.
Low operating limit voltage
VCC=0.8V
Watch dog stop function (RCT pin) included
Long clock monitoring time
TPR (POWER ON) : TWD (clock monitoring)=1 : 5
